Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE DOUBLE-SIDED, SEVERAL STORIED TWISTING MACHINE Application May 13, 1933, Serial No. 670,948 In Germany May 28, 1932 3 Claims. (Cl. 117-26) This invention relates to a double-sided twisting machine with several superposed rows of twisting spindles and winding devices arranged thereover. Such twisting machines'are in themselves known. However, in these known machines the machine frames are of cast iron and owin to their peculian construction the machine is of great width. It has already been proposed to employ within the machine single columns of cast iron frames which, however, have still a certain constructional width which nevertheless is far exceeded by the width of the driving frame so that the advantage of a slightly narrower width of machine is done away with by the great width of the driving frame. These machines are open to the objection, that only a few machines and consequently correspondingly few spindles can be accommodated in acertain space. Moreover, the machines owing to the employment of cast'iron frames are heavy and consequently expensive to build. especially if the'complicated machining is taken into consideration.

These objections areovercome according to the invention in that the machine frames of a doublesided twisting machine for accommodating the spindle rails on the two sides; and drawing devices including the driving frames, each consist of sin,- gle column section iron. The frames can be made of H- or U-section iron, the flanges on each side carrying single pieces for the spindles and brackets for journalling the drawing shafts. The frames are provided with a section iron foot to impart a firm stand. It is likewise advisable to connect the individual parts of the frames by welding.

Such a machine presents the advantage that it is of very narrow width because the spindles n the two sides, the drawing devices and the driving elements are fitted on single column section irons, so that many more machines and a much larger number of spindles than heretofore can be accommodated in a certain space. Moreover, a machine with such section iron frames is of much lighter weight and cheaper to build, particularly as no special machining is necessary.

An embodiment of the invention is illustratedv by way of example in the only figure of the accompanying drawing which shows:

A double-sided, several storied twisting machine in cross-section.

The machine frames a are each made of a single column section iron of H- or U-shaped cross section, each section iron having a foot b also made of section iron. on the flanges c, d of the section iron frames a angle pieces e, j for accommodating the spindles i, 12' are arranged one above the other for the double-sided construction of the machine, whereas brackets are bolted on these flanges for carrying the drawing devices g, h. All the frames including the driving frames are of similar construction. 15

I claim:--

1. A double-sided twisting machine with several superposed rows of twisting spindles and winding devices arrangedthereover, comprising in combination with the spindles and the winding shafts, vertical columns, each made of section iron of H-cross section having a flange on each side, angle pieces mounted on said flanges adapted to carry said twisting spindles, and brackets on said flanges adapted tocarry said winding shafts.

2. A double-sided twisting machine with several superposed rows of twisting spindles and winding devices arranged thereover, comprising in combination with the spindles and the winding devices, vertical columns, each made of section iron of U-cross section having a flange on each side, angle pieces mounted on said flanges adapted to carry said twisting spindles, and brackets on said flanges to carry said winding devices.

3. A double-sided twisting machine with several superposed rows of twisting spindles and winding devices arranged thereover, comprising in combination with the spindle rails on the two sides and the winding devices, machine frames carrying said rails and winding devices, each frame consisting of a single column of section iron of angle cross section, and a foot of section iron of angle cross section on each of said columns. 4
